Climatronic fault

Hi

I own a octavia vrs but im after information for my sisters car.

Im wondering if anyone has had a problem with the climatronic system on there fabia. Its my sisters car she has a 1.4tdi fabia mk2. The fault is that when you put the fan on it doesnt work/ run the display flashes and the fault code is saying its to do with the blower defective control module for air bliwer or short or open circuit in wiring fault code on reader 01273.

Also how do you get to the fan

Thanks in adavance
